The behaviour of the deceleration parameter \(q\)  is plotted in
Fig. REF  showing that there is a deceleration expansion at
the early time followed by an acceleration expansion. In addition,
the transition from the deceleration phase to the acceleration one
happen at \(z\approx 0.6\)  which is consistent with recent
observations [1]}, [2]}, [3]}. As Fig. REF  shows, for
fixed \(b^2\) , the universe expansion may experience a phantom phase
at current time while \(c>1\) . Moreover, for two universes with the
same \(b^2\)  and different values of \(c\) , the universe with larger
amount of \(c\)  gets its phase transition point earlier than the
other universe. Finally, for fixed \(c\)  and for the current stage
of the universe, this model predicts that the universe expansion
phase may fall in the phantom era as a function of \(b^2\) .
